.TH VOTEQUORUM_QDEVICE_POLL 3 @BUILDDATE@ "corosync Man Page" "Corosync Cluster Engine Programmer's Manual"
.SH NAME
votequorum_qdevice_poll \- Tells votequorum the result of the quorum device poll
.SH SYNOPSIS
.B #include <corosync/votequorum.h>
.sp
.BI "int votequorum_qdevice_poll(votequorum_handle_t " handle ", const char * " name ", unsigned int " cast_vote ", votequorum_ring_id_t " ring_id ");"
.SH DESCRIPTION
The
.B votequorum_qdevice_poll
is called by the quorum device subsystem (not provided as part of votequorum) to tell
the voting system if the quorum device is present/active or not. If
.B cast_vote
is 1 then the votes for the device are included in the quorum calculation, otherwise not.
Current
.B ring_id
must be set (one get in votequorum_notification_fn callback) otherwise poll is ignored.
This routine should be called at regular intervals to ensure that the device status
is always known to votequorum. If
.B votequorum_qdevice_poll
is not called for (default) 10 seconds (or 30 seconds for sync phase) then the device will be deemed to be dead and
its votes removed from the cluster. This does not unregister the device.
The default poll time can be changed by setting the cmap variable
.B quorum.device.timeout
for normal operation or
.B quorum.device.sync_timeout
for synchronization phase.
.SH RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned.
